This extension replaces the gd thumbnail generation which is the only builtin method from 3.24 because external called ImageMagick support was dropped for security reasons. It calls the php libraries for ImageMagick support

Extension Description: For security reasons, from phpBB 3.2.4 the execution of external programs was disabled. Because of that thumbnails for images can only be generated by using php internal functions. By default, this is handled by the gd-library. But for high-quality images, using the ImageMagick function provides better results. This extension uses the php-library for ImageMagick

Today I just prepared a new version which fixed some minor validation errors. The new version also has a improved error handling (errors are written to the admin log in the acp) and rotates thumbnails automatically depending on their exif information.
